Hi, I did a swig binding for csharp. I just join the build file.
I also run some test step by step to understand howto use mlt, and howto use mlt with c#. What can I do for now ? (see file mlt test step 1) - simple play video - simple Xml Out - simple Play With Filter - simple Play With Patial Filter (not all the video) - simple play with a luma transition between 2 video files - simple render file with a luma transition between 2 video files - Multitrack Play I have some problems to : Display a simple black colour Display a singlle jpg image Import and deserialize a mlt xml file I will send another mails ... Steeve
build
